❹ 人教版八年級英語上冊第四單元語法!!急!!要各個單詞的用法!!
火眼金睛:
1.「花銷」細盤點:
spend,take,cost和pay的用法:
初中階段關於「花錢」,「花費時間」的詞常見的有以下五個:buy,cost,pay(for),spend和take。很多學生對這幾個詞的詞義和用法似懂非懂,用起來往往出錯。其實這些詞都與錢物有關,與時間有關的只有take和spend。下面具體談一談其用法:①spend指花錢,花費時間。主語是人。其常見結構分別為to spend money on sth.,spend time(in)doing sth.。
I spent six yuan on a new dictionary.
—How do you spend your spare time?
—I spend my spare time writing books.②take指花錢(=cost)
It takes/costs me a lot of money to buy a big house.
= To buy a big house takes/costs me a lot of money.
take用來說明做某事需要多少時間,有三種不同的結構:
1)主語是人
She took the whole day to read the novel.(她花了一整天那本小說。)
2)主語是某種活動
The journey took me half an hour.
Reading the novel took her the whole day.
3)用形式主語it
It took me half an hour to get home yesterday.
It takes much time to do the shopping.
③pay(for),pay表示付給人家錢、帳單等;pay for表示買東西付款,也表示替別人付錢。主語是人。其常見結構是to pay sb.some money,pay money for sth.
You must pay me 100yuan a week for your meals.
How much did you pay for that book? ④cost指花錢,表示價值或代價(此代價可以是時間)。主語是事或物或動詞不定式短語。
其常見結構是to cost sb.some money。
The dictionary cost me 6yuan.
【小試牛刀】翻譯:(1)我六十元錢買了一本詞典 (五種譯法)
(2)讀這本書花了我一整天的時間 (四種譯法)
(Keys:
(1)a.I bought the dictionary for 60 yuan.
b.The dictionary cost me 60 yuan.
c.I paid 60 yuan for the dictionary.
d.I spent 60yuan on the dictionary.
e.It took me60 yuan to buy the dictionary.
(2)a.I spent the whole day reading the book.
b.I took the whole day to read the book.
c.Reading the book took me the whole day.
d.It took me the whole day to read the book.)
2.「數目」要說清:
a number of…「許多」與the number of…「……的數字/數目」這兩個片語的用法要分清:
①a number of…意思是「一些,若干」(= some),後接可數名詞復數或代詞,謂語動詞用復數形式。
a number of…片語中還可以加入形容詞表示數量大或小等(例如:a large/small number of…許多/少數……)。
②the number of…意思是「……的數字/數目」,介詞of同其後名詞構成介詞短語,修飾the number.當它作主語時,謂語動詞用單數。例如: Many people took part in 10,000-metre race, but only a number of them kept on running to the end. 許多人參加了10000米跑,但只有一些人堅持跑到底。
A number of my friends think I should take a holiday.
我的一些朋友認為我應該休假。
The number of students is about forty.學生人數大約是40人左右。
3.到達路線有幾條:
arrive in/at,get to;reach意為「抵達,到達」,我們在句子中要正確運用。
【辨析】 arrive vi.到達什麼地方,後接in或at,大的地方用in,小的地方用at;reach vt.後接地點名詞;get to也可表示「到達」,後接地點名詞,比以上兩詞更口語化,也可用get加副詞(home,here,there等)。
題例:When did you __________ home?
A. go to B.arrive at C.reach in D.reach
【解析】 在英語中「到達」可表達為get to,arrive in/at和reach。get和ararrive是不及物動詞,所以後面接賓語時,應藉助於介詞。而reach是及物動詞,它後面可以直接跟賓語。但是本題的home是副詞,副詞前不可以有介詞,所以此題的正確答案是D。
【拓展】arrive一詞除了表示「到達」外還有「來到」、「出生」的意思:
Good weather is arriving.好天氣就要來了。
My baby arrived last night.我的寶寶是昨天夜裡出生的。
Too swift(快的) arrives as tardy(遲緩的) as too slow.
[諺語]欲速則不達。
4.條條大路通羅馬:(All Roads Lead to Rome)

類似的片語還有:on an elephant騎象;on a camel騎駱駝。
二、 用動詞表示。

類似的表達還有:take a ship(乘輪船),take a plane(乘飛機)等。

II:就劃線部分提問。

2.Ann is going shopping on foot.(對劃線部分提問)
(Keys:I: 1.By 2.by 3.in 4.on /by 5.Take
II: 1. How does Mr Green go to the post office?
2. How is Ann going shopping ? )
5.否定也「溫柔」:
「not all」是一個部分否定,可見否定也「溫柔」。例如:In North America,not all students take the bus to school. (在北美,並非所有的學生都乘車上學。)
英語中的部分否定(即不完全否定)有如下一些表示方法:
一 )all 的否定式:not all…(或:all…not)表示"並非都……"、"不是所有的都……" 例如: Not all bamboo grows tall. 並非所有的竹子都會長很高。
二)both 的否定式:not…both (或:both… not) "並非兩個……都……" 例如:
I don't want both the books. 我不是兩本書都要。
Both (the) windows are not open. 兩扇窗子並不都開著。
三) every…的否定式: "不是每……都……" 例如:
Not everyone likes this book. 並非人人都喜歡這本書。
This flower is not seen everywhere. 這花並不是隨處可見的。
四) always的否定式: "並非總是(並非一直)……" 例如:
He is not always so sad. 他並不是一直都這樣悲傷。
五) all the time 的否定式: "並非一直……"、"未必老是……" 例如:
A foolish man doesn't make a mistake all the time.
笨人未必老是犯錯誤。
六) not…and…的否定式,被否定的往往是and後面的那一部分。 例如:
He did not speak clearly and correctly. 他講得清楚但不正確。
She cannot sing and dance. 她會唱歌但不會跳舞。
如果將and 換成or,not 對其後面的兩部分就全盤否定了。
He did not speak clearly or correctly. 他講的既不清楚也不正確。
【注意】 如要對上述的all, both, every, always, 以及entirely, altogether, completely, quite 和 all the time 等詞作完全否定,那就分別要用與之相對應的全否定詞,如no, none, neither, no one, never, not (never)… at all 等。例如:
All of them can do it.--- None of them can do it.
Both are good.---Neither is good.
Everybody likes it. ---Nobody likes it.
He is always late. --- He is never late.
We don't trust them entirely. --- We never trust them at all.

35. 在水稻種植界, 中國科學家袁隆平堪稱為是一個領軍人物 / 傑出人物。
36. 他認為, 解決人們吃飯問題的關鍵在於擁有更多的稻米, 並且能更快地生產出來。
37. 他認為只有一種方法可以做到這一點—對不同種類的水稻進行雜交。
38. 全國各地的研究人員被召集到一起, 共同研究這項新體系。
39. 由於袁隆平的發現,中國的水稻產量在20世紀90年代增長了47.5%。
40. 五萬平方千米的稻田轉而種起了蔬菜及其它經濟作物。
41. 在巴基斯坦, 水稻是繼小麥之後的第二大作物, 而且將在這個國家的許多地區種植。
42. 當今, 火箭是非常先進的器械, 我們可以用來向太空派送宇航員。
43. 中國人發明了一種火葯, 它可以在節日期間被裝進竹筒扔進火里發出(噼里啪啦的)爆炸聲。
44. 中國人發現, 從竹筒里跑出來的空氣可以把它推向空中。
45. 竹筒被系在一根長棍子上, 它利於保持火箭直向飛行。
46. 一位義大利科學家甚至發明了一種能夠在水面上飛行並擊中敵艦的火箭。
47. 但是並非每個人都想在戰爭中運用火箭。
48. 萬胡在爆炸中死掉了? 還是被帶往空中幾英里的地方, 成為世界上第一位宇航員?
